download unter www.biologiezentrum.at Zoological Museum of the Moscow State University (ZMUM) have been incorporated in the study as well Altogether, 15 species have been found and treated in the region concerned, of which three are nevv to science The cryptophagid fauna of lndia is currently known to contain eight genera: Antherophagus, Cryptophagus, Micrambe, Henoticus, Himascelis, Caenoscelis, Alomaria, and Curelius Almost all these genera are pandemic in distribution, but at the species level the fauna of the Oriental realy differs considerably from the Palaearctic one Keys to species of a few genera already exist, though of varying quality (JOHNSON 1970, SEN GUPTA 1980) Acknowledgements am very grateful to Dr W SCHAWALLER (Stuttgart) for sending me material for study, to Dr S GOLOVATCH (Moscow) for the help both in locating some references and checking the English of an earlier draft, and to the International Science Foundation for awarding me a subsidiary grant (MF-4000) Cryptophagus HERBST, 1792 The Indian fauna of Cryptophagus is relatively rieh, with 13 acknowledged species: anxiosus GROUVELLE, 1916, atratus CHAMPION, 1922, auropubens GROUVELLE, 1916, bengalensis SEN GUPTA, 1980, braminus MOTSCHULSKY, 1858, ceylonicus MOTSCHULSKY, 1866, clavator CHAMPION, 1924, himalaicus BRUCE, 1952, johnsoni SEN GUPTA, 1980, lomus SEN GUPTA, 1980, martensi SEN GUPTA, 1980, paralklicollis GROU- VELLE, 1916, Simulator GROUVELLE, 1916 As shown by BRUCE (1938), several congeners introduced by GROUVELLE were actually junior synonyms of some others All four species from lndia and Nepal proposed by SEN GUPTA (1980) are extremely difficult to recognize, for they have been described on the basis of a few speeimens, some of them only from a Single female holotype Even when the males were present in the type series, their aedeagi were omitted, nor were they depicted The differences berween SEN GUPTA'S species were often based on struetures displaying a pronounced intraspeeifie Variation Thus, even without having seen/revised the types of those four formal congeners, I dare predict that at least some of SEN GUPTA'S species might prove to actually represent but junior syno-nyms of the extremely widespread C laticollis LUCAS, 1848 For the same reason, a key to Indian Cryptophagus species cannot be elaborated until the types of the species named both by GROUVELLE and SEN GUPTA have been reexamined Therefore, below is only the description of a new species and several new records of Indian Cryptophagus Cryptophagus atratus CHAMPION, 1922 (figs 1-2) Material: lndia, Himachal Pradesh, Simla, Kufri, 16.VII.1989 leg A RIEDEL, 15 ex SMNS, ex ZSM, 6ex ZMUM Habitus as in fig Male genitalia: Aedeagus has hitherto not been described, as in flg Distribution: lndia Remarks: C atratus differs from the related auropubens GROUVELLE, 1916 in having the callosity on the pronotum pointed (blunt in auropubens) and by the more strongly transverse joints of the antennal club Cryptophagus aurovestitus BRUCE, 1945 (fig 3) Material: lndia, Uttar Pradesh, Badrinath, 3200-3600 m, 1.VIII 1989 leg A RIEDEL, ex SMNS Distribution: lndia, Burma 50 © Entomofauna Ansfelden/Austria;

from parallelicollis by the structure of the prothorax (parallel-sided in parallelicollis, lateral tooth behind middle of lateral margin) While auropubens is dark in coloration, Simulator is light red-brown All SEN GUPTA'S species differ from Simulator by the erect pubescence; Simulator is similar to robustus BRUCE, 1959, but differs from it by the structure of the aedeagus (curved parameres); himalaicus sometimes differs from Simulator by the less strongly transverse prothorax and the more transverse lOth Joint of the antenna, but the size of the facettes and the structure of the aedeagus are more secure characters The facettes of Simulator are smaller, the punctures on the prothorax are larger than an individual facette Cryptophagus heteroclitus sp nov (figs 5-6) Holotype cf: India,Himachal Pradesh, Simla,Kufri,16.VH.1989 Ieg.A.RiEDEL (SMNS) Paratypes: Same data as holotype, ex SMNS, ex ZSM, ex ZMUM Description: Body broadly elongate (flg 5), slightly convex;
